Yes I start already a research for a power supply. But have to find a good universal one, I could also use for other things (in case of). Changing voltage and polarity, etc. I already got such a power supply but it has only 1V, 1,5V, 3V, 4,5V, 6V, 9V and 12V. But 4,5V is to low and 6V to much.
Here another test with my shitty slow Z4 box. With my own ROM I get always only 30K @ AnTuTu 6.3.3 (WTF?)
[ Test Result ]
ROM: Shomari Z4 4PDA (OC & T8C)
Power: Stock power supply 5V 2A
Stress CPU: OC > Reboot after 20 - 30 sec.
Stress CPU: T8C > Reboot after 10 sec.
Pretty shitty results, compared to yours.
I also opened the box after I re-flashd my own V2 rom and did some Stress CPU tests again and checked also Kernel Auditor.
After a few minutes the clock speed went pretty down (both cluster max 600) but it stayed stable. Quit the test after 3h. But that small heatsink went also pretty hot. Maybe this box has an heat issue, or the heatsink isn't fixed properly? Will check also for a better heatsink, that covers the ram as well. The box has also this big metal plate inside. I think it's something like a heat collector. Because of that, there isn't much space for higher heatsink. Or I have to remove the metal plate!? Will check.
Android is Java on Linux. Lets say splitted in 3 level. On the top the bling bling APK (level 3). In the middle the Java Framework (level 2) and at thebasement Linux (level 1)
So there are a lot of options to port a rom. Especial while the interfaces between these levels have to talk always in the same way.
And my first problem was not the dtd, becasue I dind't touch any of the 1 level at the beginnig. Only Framework and my level 3 bling bling.
To get samba and App2SD running, I had only to change to vold, Because in your ROM, there isn't a mount point for external_SD to use as system mount point. Only as removable SD card.
I know the code of your ROM already pretty good. Mostly pretty clean. Only a few hidden fully loaded corps. But not used at all.
BTW I search already for a full dump of the V99 Hero. But so far no luck. But right now I first have to check why my box is so damn slow ...

Do you know the reason why AnTuTu plays no sound? Or only a few time annoying noise. like you send raw audio to spdif but it accepts only pcm. Not with your rom. I'm struggling a bit with my other Yundo Y1 S912 project.
There's no heat throttling in my firmware (remember, I literally took it out). What app do you use to 'stress' the CPU?
Any heatsink would do fine, and I don't recommend anyone use that 4PDA build, as I've said, use the updated ones, especially if you have a Z4.
I haven't had any reason to check heat in months, literally, because I've never had any issues and it's only very recently that I've seen the odd report of suspected heat problems, but it's always someone saying the device suddenly shut off, which I know is not what heat throttling does.
I'm not making any changes at this point on that front. I even used a stress test app a day or two ago, one that stresses the cpu/gpu simultaneously. I couldn't reproduce any issues at all.
